PixlRun / Free tool
Split any photo into a full-resolution Instagram carousel.
Drop a wide photo below, pick how many slides (2-10) and square or 4:5, and PixlRun cuts it into a ready-to-post carousel - entirely inside your browser. No account, no watermark, and every slide keeps your original photo's full resolution instead of a shrunken, recompressed copy.
Drop a wide photo here or click to choose
JPG, PNG or WebP - one photo at a time, sliced into your carousel.
This photo isn't tall enough for this many slides at this aspect ratio without upscaling - using the full available height instead. Try fewer slides or switch to Square for a perfect crop.

Why full resolution matters
Most mobile carousel-splitter apps are genuinely useful, but many of them compress or resize your photo before splitting it - a common complaint from users who notice their split slides look softer than the original photo once posted. That happens because those apps run your image through their own compression pipeline, often to save server bandwidth or storage, before handing back the pieces.
PixlRun's Carousel Splitter never uploads your photo anywhere. It crops directly in your browser using your original photo's own pixels, so nothing gets shrunk or recompressed away before you download it.
How it works
Drop in a wide photo and pick how many slides you want (2-10) and which aspect ratio - square or 4:5 portrait. PixlRun instantly slices your photo into that many equal-width pieces directly on a canvas element in your browser, cropping each one to your chosen aspect ratio from your photo's own full-resolution pixels - no resizing, no server round-trip.
If your photo is taller than a slide needs, drag the crop position slider to control exactly what part of the photo shows in each slide. When you're happy with the preview, download each slide individually or grab all of them at once as a ZIP file (built on-device with the open-source JSZip library).
Extremely large photos (roughly 48 megapixels and above) are automatically scaled down to fit browser memory limits, the same safety cap used across PixlRun's other on-device tools.
FAQ
How many slides can I split a photo into?
Anywhere from 2 to 10. When you drop in a photo, PixlRun automatically suggests the most slides your photo's width can support while keeping every slide at or above Instagram's own recommended minimum resolution (1080px wide) - so you never end up with a slide so narrow it would need to be upscaled. You can always override the suggestion and pick any count from 2 to 10 yourself.
Does splitting my photo lose quality?
No. Every slide is cropped from your original photo at its exact original pixel resolution - nothing is downscaled or upscaled. That's different from many carousel splitter apps, which resize and recompress your photo before cutting it up, so the pieces you download are smaller and softer than your source photo. By default, slides export as JPEG at 95% quality (visually indistinguishable from the source); switch to PNG in the export options for byte-for-byte lossless files.
Is there a watermark on the exported slides?
No, never - on the free tier or on Pro.
Is my photo uploaded to a server?
No. Splitting happens entirely on-device using your browser's canvas - your photo is decoded, cropped and re-encoded locally, and is never sent anywhere. The only things this page downloads are its own code and the JSZip library (used only for the optional "Download all" button).
Should I use 4:5 (portrait) or 1:1 (square)?
Either works for an Instagram carousel - 4:5 takes up more vertical space in the feed (more attention per slide), while 1:1 keeps a clean, even grid on your profile. If you're not sure, 1:1 is the safer default since it matches how most single-image posts already look on a profile grid.
